Didn't some version of the 215 end up in the Morgan +8? I helped a USAF friend campaign a 1968 Morgan +4 in central California autocross racing when we were both stationed at Castle AFB. The +4 ran a somewhat beaned-up Triumph 4 cylinder engine.
Those Triumph (Ferguson Tractor) engines have plenty of potential- I had a warmed-over TR-3A as a kid, and I loved that car.
